To all whom it mrtg/concern,.-

Be it known that I, JOHN A. HYTER,a citizen of the United States,residing at Fostoria, in the county of Wood and State of Ohio,haveinvented certain new and useful Improvements in Steam-Engines; andI dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improved doubleacting vibrating compressedair or steam engine; and the object is to increase the efficiency andmotor-power by simplifying and improving the construction of themachine.

To these ends the invention consists in the construction, combination,and arrangement of the several parts of the device, as will behereinafter more fully described, and particularly pointed out in theappended claim.

In the accompanying drawings, the same reference characters indicate thesame parts of the device.

Figure 1 is a side elevation, partly in section, of an engine embodyingmy invention. Fig. 2 is a top plan view, also partly in section, of thesame.

In the drawings, 1 denotes the cast-metal frame, provided with thebearings 2 2 to receive the driving-shaft 3, provided with thel usualbalance-wheel 4 and the crank-disks 5 and 6, to which theconnecting-rods 7 and 8 are pivoted, and which extend to theoppositely-disposed cranks 9 and 10, IiXed on the alined shafts 12 and13, journaled in the bearings 14 15 on the frame 1.

16 and 17 denote the intermeshing vibrating pistons, fixed on thecontiguous ends of the piston-shafts 12 and 13, and they are providedwith the radial overlapping pistonblades 16' and 17', which have abearing in the cylinder 18. This cylinder is provided with duplicatesteam-chests 19, which are supplied with steam or compressed air throughthe branch pipes 21 21', communicating with the main steam-pipe 22,which is provided with the usual throttle-valve and the governor-valve23, operated by the belt 24, coacting with the pulley 25 on the mainshaft 3.

26, 27, and 2S denote one set of steam inlet and exhaust ports, and 29denotes the slidevalve, the stem of which terminates in a guideblock30,' working in a guide 31 on the brace 32, fixed to the frame.

The guide-block 30 is formed with a lateral 5 5 arm 33, which isconnected to the rod 34, pivoted to the upper end of a rocking lever 35,operated by the usual eccentric, rod, strap,` and the eccentric Xed onthe main drivingshaft 3. n

26', 27', and 28' denote the other set of inlet and exhaust ports, and29' a coacting slidevalve, the stem of which terminates in a guide;block 39', working in a guide 31' on the lower end of the brace 32. Theguide-block 30' is provided with a lateral arm 33', which is connectedto the rod 3l', pivoted to the lower end of the rocking lever 35.

In operation, the steam is admitted between the contiguous pistonbladesthrough the ports 26 and 27', Whichtends to separate them and at thesame time close up the opposite piston-blades in line with the ports 27and 26'. The slide-valves have now changed their positionto open theports 27 and 26', while the ports 26 and 27 are placed in communicationwith their respective exhaust-ports. The steam now enters through theports 27 and 26', thereby separating the contiguous pistonblades anddriving them back to their former 8o position, and so on, the movementsof the pistons and their respective shafts being communicated to themain driving-shaft through thel medium of the connecting-rods 7 and 8.

It will of course be understood that various changes in the form,proportion,and the minor details of construction may be resorted towithout departing from the principle or sacrivficing any of theadvantages of this invention.

Having thus described the invention, what 9o is claimed, and desired tobe secured by Letters Patent of the United States, is

In a double-acting vibratorengine,the main driving-shaft 3, thecrank-disks 5 and 6, and

the connecting-rods 7 and 8 5 in combination 95 with the oscillatingshafts 1213 and their cranks 9 and 10, the cylinder 18 provided withduplicate inlet and exhaust ports and coacting slide-valves,their stems,the rocking lever 35 connecting said stems, a single eccentric IOOmounted on the main driving-shaft and op- In testimony whereofI llavehereunto set eratively connected to said lever and adapted my hand inpresence of two subscribing Wit to simultaneously reciprocate saidValves in messes.
